摘要
Abstract
A large number of unknown goaf areas formed in the random mining area of coal mine area, which are the causes of geological disasters such as ground collapse and ground fissure.In coal mining areas, underground caves are mainly coal mine goaf areas, showing the condition of being filled and not filled with accumulated water under the influence of hydrogeological conditions and exploration time.Due to the influence of hydrogeological conditions and mining time, the goafs present two statuses: filled and not filled with water.By using transient electromagnetic method, the goafs in Shendong mining area were investigated and explored, and the most primitive normalized secondary potential was used to explain the goafs filled and not filled with water.According to the time length of underground cavity development and the level of accumulated water, it will present high or low resistivity anomaly, showing striking features. It provides an example for the application of transient electromagnetic method in the exploration of goaf and goaf filled with water, and it is of great significance to predict and prevent the collapse geological disaster caused by the goaf.关键词
